How to count elements?

[dynabler]

Scenario: you want to count the number of elements on a page, a div.card or table.tr. JavaScipt has a count method: https://www.geeksforgeeks.org/collect-js-count-function/

I can't seem to get it working in Flyscrape. How would you do it?

The way you count elements in JavaScript / Flyscrape is:

const numberOfCards = doc.find(".card").length;
const numberOfTableRows = doc.find("table tr").length;
